Symptoms
Loading sys config triggered by MCPD start might fail after removing NICs for VE if the given NICs have been configured as the data-plane interfaces in BIG-IP Virtual Edition (VE).
Impact
BIG-IP VE stops working. BIG-IP VE cannot be in ready state since almost all other services depend on MCPD to be up running first.
Conditions
- BIG-IP VE.
- Multi-NICs have been configured as the data-plane interfaces.
- One or some of these NICs have been removed from the host side.
Workaround
Edit /config/bigip_base.conf to delete the net interfaces that have been removed on the host/hypervisor side.
To work around this issue, you can edit the /config/bigip_base.conf file and remove the interface that is causing the error. To do so, perform the following procedure:
Impact of workaround: Performing the following procedure should not have a negative impact on your system.
1. Log in to the Advanced Shell (bash) of the BIG-IP VE system.
2. Use a text editor to open the /config/bigip_base.conf file.
3. Look for an entry that uses the following syntax:
net interface <number> {
media-fixed <setting>
}
For example:
net interface 1.2 {
media-fixed 10000T-FD
}
4. Delete the stanza.
5. Save the text file.
6. Load the configuration by typing the following command:
tmsh load sys config
